• Searches by keyword, year and category may be performed
simultaneously and in any combination.The results are ordered chronologically.

• Any keyword (or combination of keywords) may be used. Keywords of three characters
or less are ignored.

• When the keyword box is left blank and the year and category are left as is, all the entries
with known dates are shown.

• Finally: The Timeline is a work in progress. A
number of entries currently have no identified date, and are therefore
listed with a year of zero (0). To view them, put 0 in the first (left)
year box.
